Steven Hawkins updated TEIID-4244:
----------------------------------
Steps to Reproduce:
1. In postgresql create the test_a table by the following script:
{code:sql}
CREATE TABLE test_a
(
a integer,
b integer
);
INSERT INTO test_a(a, b) VALUES (1, 1);
INSERT INTO test_a(a, b) VALUES (1, 2);
INSERT INTO test_a(a, b) VALUES (2, 1);
INSERT INTO test_a(a, b) VALUES (2, 2);
INSERT INTO test_a(a, b) VALUES (3, 2);
INSERT INTO test_a(a, b) VALUES (3, 10);
{code}
2. Add postgresql database configuration in standalone-teiid.xml
{code:xml}
<datasource jndi-name="java:/test_pg" pool-name="test_pg" enabled="true" use-java-context="true">
<connection-url>jdbc:postgresql://localhost:5432/test?charSet=utf8</connection-url>
<driver-class>org.postgresql.Driver</driver-class>
<driver>org.postgresql</driver>
<pool>
<min-pool-size>2</min-pool-size>
<max-pool-size>70</max-pool-size>
<prefill>false</prefill>
<use-strict-min>false</use-strict-min>
<flush-strategy>FailingConnectionOnly</flush-strategy>
</pool>
<security>
<user-name>postgres</user-name>
<password>xxxxxx</password>
</security>
<validation>
<check-valid-connection-sql>select 0</check-valid-connection-sql>
</validation>
<timeout>
<blocking-timeout-millis>120000</blocking-timeout-millis>
<idle-timeout-minutes>5</idle-timeout-minutes>
</timeout>
</datasource>
{code}
3. Add in test-vdb.xml java:/test_pg configured in previous step as datasource:
{code:xml}
<model name="test_pg">
<property name="importer.useFullSchemaName" value="false"/>
<property name="importer.tableTypes" value="TABLE,VIEW"/>
<property name="importer.importKeys" value="false"/>
<source name="test_pg" translator-name="myPg" connection-jndi-name="java:/test_pg"/>
</model>
{code}
4. Run the query:
{code:sql}
select * from (select 3 as a, 3 as b union all
select 1 as a, 1 as b union all
select 3 as a, 3 as b) as t1 join test_pg.test_a t2 on t1.a=t2.a limit 10;
{code}
which will fail with ASSERTION FAILED error message. But the following query won't fail:
{code:sql}
select * from (select 1 as a, 1 as b union all
select 3 as a, 3 as b) as t1 join test_pg.test_a t2 on t1.a=t2.a;
{code}
was:
1. In postgresql create the test_a table by the following script:
{code:sql}
CREATE TABLE test_a
(
a integer,
b integer
);
INSERT INTO test_a(a, b) VALUES (1, 1);
INSERT INTO test_a(a, b) VALUES (1, 2);
INSERT INTO test_a(a, b) VALUES (2, 1);
INSERT INTO test_a(a, b) VALUES (2, 2);
INSERT INTO test_a(a, b) VALUES (3, 2);
INSERT INTO test_a(a, b) VALUES (3, 10);
{code}
2. Add postgresql database configuration in standalone-teiid.xml

{code}

select * from (select 3 as a, 3 as b union all
select 1 as a, 1 as b union all
select 3 as a, 3 as b) as t1 join test_pg.test_a t2 on t1.a=t2.a;
{code}
which will fail with ASSERTION FAILED error message. But the following query won't fail:

select * from (select 1 as a, 1 as b union all
select 3 as a, 3 as b) as t1 join test_pg.test_a t2 on t1.a=t2.a;
